Patented Sept. 13, 1932 UNITED STATES PATENT OFFICE FILM HANGER Application filed August 14, 1931.

This invention is a film hanger of the type disclosed in Letters Patent N 0. 1,508,804, granted to me September 16, 1924:, the object of the present invention being to provide a hanger which may be easily and inexpensively produced and in which the film may be easily inserted and, when inserted, will be firmly supported. The invention is illustrated in the accompanying drawing and will be hereinafter fully set forth.

In the drawing,

Figure 1 is an elevation of a hanger embodying the present invention in position within a developing jar which is shown in section,

Fig. 2 is a transverse section of the hanger on the line [2-2 of Fig. 1, and

Fig. 3 is a horizontal section of the hanger on the line of Fig. 1.

The developing jar, indicated at 1, may be of any known or approved form. The hanger an integral structure of bakelite or other material which is light and durable and of a quality to withstand the action of developing chemicals. The hanger comprises a rectangular frame having upper and lower bars 2 and end bars 3 and may be provided in various sizes corresponding to standard sizes of films. Rising from the top bar 2, adjacent the ends thereof, are suspending arms 4 which have their upper ends united with a cross bar 5 of somewhat greater length than the length of the frame and having its ends turned d ownward ly, as shown at 6, to constitute feet which may rest upon the inner ledge near the top of the developing jar so as to support the hanger within the jar. The feet 6 are also of such outline that they may be engaged over a hook or other support when it is desired to suspend the film for drying. On the opposed surfaces of the top and bottom bars 2, along the front and rear edges of the respective bars, are provided counterpart lugs or guide flanges which will direct the film into proper position as it is inserted in the hanger and will support it after it is inserted. These lugs or guide flanges include a relatively long flange or lug 7 at the rear edge of each bar and adjacent one end of the same, the right-hand end in the accompanying drawing. In stag- Serial No. 557,185.

gered relation to each lug 7 is a short lug 8 at the front edge of the respective bar, and upon referring to Fig. 3 more particularly it will be noted that one edge of the lug 8 is alined transversely with the inner end of the adjacent lug 7, and the said edge of the lug 8 is beveled, as shown at 9, whereby to facilitate the insertion of the film. In similar relation to the lug 8 but at the left of the same is a rear lug 10, the right-hand edge of which is beveled, as shown at 11. The lug or flange 10 is longer than the lug or flange 8 but appreciably shorter than the lug 7 and is alined with the lug 7, as clearly shown in Fig. 3. Lugs 12 and 13, corresponding in all essentials to the lug 10, are arranged between the lug 10 and the left-hand end of the frame and alined. respectively with the lug 8 and the lug 10. On the inner edge of that end bar 3 which appears at the left in the accompanying drawing are provided lugs or flanges 1 1 and 15, the lug 15 being disposed substantially midway the top and bottom of the frame, and the lugs 14 being disposed in staggered relation to the lug 15. The inner edges of these lugs are beveled, as indicated at 16, so that they will serve to direct the film into position and e11- gage opposite surfaces of the film so as to support it in a vertical position within the hanger and resist the tendency of the film to curl or bend. A lug 17, corresponding in form and location to the lug 15, is provided upon the right-hand end of the frame, and on said right-hand end of the frame are lugs 18 which are located above and below the lug 17 and at the front side of the end bar, so that they correspond in location to the lugs 14. The

lugs 18, however, taper toward the top and bottom of the frame, as clearly shown in Fig. 1, thereby facilitating the entrance of the film into the hanger without requiring excessive bending of the film.

In use, the film to be developed has one end inserted between the top and bottom bars of the frame in front of the lugs 7, and said end of the film is then moved along the frame toward the opposite side of the same and on a line passing between alined lugs 10 and 13 and the alined lugs 8 and 12, respectively. The film will thus be brought into position within the frame so that it will rest upon the bottom bar of the frame and its upper edge will be retained by and between the several lugs along the frame. The advancing end edge of the 5 film, as the film is brought into position between the frame, will pass between the lugs let and 15 to rest against the end bar of the frame and be held by said lugs, while the op posite end of the frame may be slightly rolled to clear the high ends of the lugs 18 and then released so that it will assume a position in front of the lug l7 and back of the lugs 18 in an obvious manner. The arrangement of the lugs facilitates the fitting of the film within the frame and also supports the film so that curling thereof will be overcome while the entire surface of the film may be treated by the developer. The top, bottom and end bars of the frame are solid so that the frame will 20 maintain its shape and will firmly support all the edges of the film which may be ins rted therein. The movement of the film into the frame is toward the beveled eeges of the several lugs, so that if it should happen to impinge against any of said lug it will be directed into the proper plan of the frame without injury, and, at the same time, the lugs are long enough to efhciently retain the film in position in the frame.

The device is a single integral structure without hinges or other moving parts which are apt to break off or catch and damage the film. The open area of the hanger ample to facilitate the insertion and pe 'mit free access of the developer to the entire surface of the film and provide for a circulation of air thereover to expedite drying. Atthe same time, the film is supported throughout its marginal extent and prevented from curling.

40 Having thus described the invention, I

claim:

1. A film hanger comprising a frame consisting of top, bottom and end bars, and filmretaining lugs on the inner sides of all said bars along the opposite edges of the same and in staggered relation, each lug having one edge beveled.

2. A him hanger comprising a frame consisting of top, bottom and end bars, the top and bottom bars being provided with lugs arranged in staggered relation along their front and rear sides, the lugs adjacent one end of the frame being relatively long and the remaining lugs having their edges presented to the relatively long lugs beveled and the end bars being provided with inwardly extending lugs arranged in staggered relation along their front and rear sides, the upper and lower lugs adjacent the relatively long lugs 01.

the top and bottom bars being tapered toward the top and bottom bars.

In testimony whereof I afiix my signature.
